Rangoon’s northern district court ordered on Friday that the police reexamine the case surrounding the fugitive Aung Win Khaing in the U Ko Ni murder trial, including a nationwide search if necessary.

Last week, the Rangoon Division High Court rejected the petition from lawyer U Nay La—representing the family of the assassinated National League for Democracy (NLD) legal adviser U Ko Ni— requesting a new arrest warrant be issued in Naypyidaw for the fugitive.

Aung Win Khaing is suspected of involvement in the murder but remains at large. He was last seen in Naypyidaw, according to CCTV footage.

“Even though the High Court refused to issue a new arrest warrant, it ruled that the investigation of fugitive Aung Win Khaing [prior to the trial] was insufficient,” U Nay La told The Irrawaddy after the hearing at the northern district court on Friday.

“In accordance with the ruling of the High Court, the northern district court ordered [the police] that the search for the fugitive Aung Win Khaing be carried out again more thoroughly,” he explained.

Before the trial in early March, U Nay La initially requested that the northern district court issue the warrant in Naypyidaw, but the court ruled against the move.
